How to align addContentView at the screen's bottom in Android

Question

I would like to ask something about the addContentView() command. I have created a custom view apparted from a LinearLayout(fill parent, wrap content) in vertical mode and some buttons.

My question: Is it possible to place my custom view at the bottom of the screen by using the addContentView() command?

I now use addContentView() but my custom view is placed at the top of my screen. I have already tried to change the height of the custom view in fill parent but then I have a full screen custom view.

Answer 1

Solution is to wrap your custom view in a RelativeLayout that fills whole screen and then add it with addContentView. For example to add a custom Button on the bottom of the screen:

// Fake empty container layout
RelativeLayout lContainerLayout = new RelativeLayout(this);
lContainerLayout.setLayoutParams(new RelativeLayout.LayoutParams( LayoutParams.FILL_PARENT , LayoutParams.FILL_PARENT ));

// Custom view
Button mCustomView = new Button(this);
mCustomView.setText("Test");
LayoutParams lButtonParams = new RelativeLayout.LayoutParams( LayoutParams.WRAP_CONTENT , LayoutParams.WRAP_CONTENT );
lButtonParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
mCustomView.setLayoutParams(lButtonParams);
lContainerLayout.addView(mCustomView);

// Adding full screen container
addContentView(lContainerLayout, new LayoutParams( LayoutParams.FILL_PARENT , LayoutParams.FILL_PARENT ) );

This should make it

Try with the folowing code

LayoutParams lp =new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
        lp.gravity=Gravity.BOTTOM;
        addContentView(b, lp); 

Using RelativeLayout also you can achieve same. You can add rule to set view at the bottom of parent layout.
